IPC: G02B6/38
Filed: 1985-01-21
Abstract: PURPOSE:To shorten a polishing time while setting optical fibers in an abutting state with high contacting pressure by chambering the projecting tip of a hollow stylus. CONSTITUTION:A ferrule body 20 consists of a metallic or plastic external cylinder 28 having a cord through hole 24 where an optical cord 22 runs and a large fiber through a hole 26 where the exposed optical fiber 22a of the optical cord 22 runs and plural hollow styli 30 which are made of metal, e.g. copper alloy and deform elastically in the radial direction by being inserted into the external cylinder 28 to position an optical fiber 22a. Tips 30a of the hollow styli 30 are chambered and made small in sectional area, so the quantity of polishing is small when the ferrule 10 is polished at right angles to the axis and the ferrule is polished in a short time. Consequently, the operability is good and the optical fiber is placed in the abutting state with large contacting pressure, so the abutting operation becomes secure.

Abstract: PURPOSE:To stably obtain an operating layer whose carrier concentration profile in the depth direction is sufficiently sharp, by implanting impurity ions in one main surface of a substrate, sticking a high melting point conductor film on the main surface, making a current flow through said film to generate heat, and activating the impurity ions with said heat. CONSTITUTION:The following are contained; a process implanting impurity ions in one main surface of an insulative or semiinsulative semiconductive substrate 1, a process sticking a high melting point conductor film 3 on the main surface, and an annealing process to activate the implanted impurity ions with heat generated by making a current flow through the conductor film 3. The amount of heat at the time of annealing can be controlled by adjusting power and period of high frequency and the thickness of a tungsten nitride (WN) film 3. Since the WN film 3 is in close contact with an N-type implantation layer 2, heat transfer is also effective. Hence the short time annealing is realized as compared with the annealing method using a heater installed outside a quartz tube, and the stability is excellent as compared with the method using an infrared radiation lamp, so that the N-type operating layer whose carrier concentration profile in the depth direction is sharp can be stably obtained.

Afterwards, a source switching circuit 1 is switched to a source B with, for example, a selector switch 7, a system controller 5 outputs a correction command as a substitute for a monitor command. The attenuating means 14 to which the correction command has been inputted compares the amplitude value of sound volume data from a sound volume adjusting means with the output dynamic range stored in the RAM 13. The attenuating means 14 attenuates an output waveform by, for example, -6dB when the amplitude value of the output waveform exceeds the output dynamic range.
